I would like to re-learn C by programming the examples in the newest Deitel & Deitel C How To Program book (5/e) on my MAC PB. How do I get started? I gather that GCC is on the MAC Developer tools, but frankly, my Unix usage is over 20 years old and I need some hand holding. I am not sure how to get the developer tools going, either from the MAC GUI, or from a Terminal window. In other words, how do I compile and run a simple "Hello World/n" printf statement on the PB?
